Find LCM of 572,432,234,691 with Prime Factorization
| 2 | 572, 432, 234, 691 |
| 2 | 286, 216, 117, 691 |
| 3 | 143, 108, 117, 691 |
| 3 | 143, 36, 39, 691 |
| 13 | 143, 12, 13, 691 |
| 11, 12, 1, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 13 x 11 x 12 x 1 x 691 = 42687216
Therefore, the lowest common multiple of 572,432,234,691 is 42687216.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
572 x 432 x 234 x 691 = 39955234176
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
234 : 1, 2, 3, 6, 9, 13, 18, 26, 39, 78, 117, 234
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,432,234,691, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
432:2x 2x 2x 2x 3x 3x 3
234:2x 3x 3x 13
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 13 = 936
Therefore, the value for common factors is 936.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 39955234176/(1x936)
LCM = 39955234176/936
LCM = 42687216
Thus, we can understand that the LCM of 572,432,234,691 is 42687216.
